Two new triterpenes, 3β,19α,23-trihydroxy-urs-12-ene (1) and 3β-(p-hydroxy-c/s-cinnamoyloxy) urs-12-en-28-oic acid (2) have been isolated from the methanolic extract of Mimusops elengi along with 3β-(p-hydroxy-trans-cinnamoyloxy)urs-12-en-28-oic acid (3), which has been obtained for the first time from this species, and ursolic acid (4), respectively. Their structures were established through chemical and spectral studies. Compounds (3) and (4) were found to exhibit potent inhibitory activity against α-glucosidase enzyme.
